I doubt that 2020 is going to be an altcoin year or other digital currency only because we're in a new year. Which happened and what prompted all of the cryptos to go up and down will continue to do so in 2020. When there's a buzz, the price goes up for everyone to buy. There's simply no bitcoin in between zone when there's a fud and everyone starts selling it down. Now there's fud so bitcoin price doesn't recover.
